The letter A on said figure is a representation of a large eye, formedby anenLrgemcnt of the needle Letter B is a small eye near the point ofthe needle, in which the thread is held-when the needle is at work. i v

Letter is a'slit extending from the large eye A,

to the small eye B, and entering the eyeB on one side thereof. 7

There is agroovc on one side of my needle, also extending from eye A toeye B.

My device is operated as follows: When I desire to thread the needle, Ipass the end .of the thread through the large eye 'A., I thel'i takehold of the thread on each side of the needle "and force it down-theslit C-until it reaches and rests in the eye B.

\Vhat I claim as my invention, and desire to secure by Letters Patent,is'

.The sewing-machine needle herein described, having the large upper eyeA, and the srnall lower eye B, connected by the slit 0, as described,and for the OHAR LES'R. S. 'OURTIS. Witnesses: g l R. Butrz,
